"AUTOMOBILE HEADLIGHT.

Application filed May 18,1926. Serial No. 109,918.

My present invention pertains to automobile headlights, and contemplatesthe provision of a headlight which while simple and 'inexpensive inconstruction and capable of" adequately lighting the road in front of anautomobile, is so characterized as to avert glare in front of and at theSide of the line of the vertical center of. the headlight.-

7 To the attainment of the foregoing,the 10 invent on consists 1ntheimprovementas hereinafter described and definitely claimed. In theaccompanying drawings, forming, part of this specification Figure 1 is alongitudlnal' vertical central section ofthe headlight constituting thepreferred embodiment of my invention. Figure 2 is afront end elevationof the headlight.

As illustrated in Figure 1, my novel head- 20, light is madeup of acasing 1, closed at its back and open atits front, an incandescentelectric lamp 2 arranged in the upper rear portion of the casing andcarried by a socket '3 attached to the back. wall of the casing, a

' reflector 4 disposed in the casing 1 and about the socket 3 and openat its forward end, alens 5, and a lens holder 6, the said holder 6being joined preferably in detachable man- .ner to the ,casingl andbeing adaptedto normally hold the lens 5 in the relative positionillustrated, that is to say with therear side of the lens 5 abuttingagainst the forward end of the reflector 4 and the forward end of thecasing and closing the open end ofthe reflector.

While I show the reflector 4 as formed in one piece, I would have itunderstood that it is within the purview of my invention to form thereflector 4 in-longitudinal sections, the longitudinal edges ofthe saidsections being abutted and appropriately joined.

The reflector 4 is of the general eonfiguration illustrated, and istapered toward its rear end and is arranged in the' casing 1 in agenerally inclined position. The entire innor surface of the element 4isreflective in character so as tocontribute to the illuminating qualityof the headlight.

' As will be appreciated from Figure 1, the major fportion of theforwardopen end of there ector 4 is disposed in a horizontal plane below thatin which the lamp 2 is 10- cated, and from'this it follows that the forwardupper portion of the reflector 4 will tend to cast the lightraysfor-wardly and downwardly, and will prevent the projeclucent as desiwill be noted t at the said frosted or colored 'ture from my invention.

tion of a large portionof the light rays directly forward in ahorizontalplane from thelamp2.

As will be understood by comparison of to Figures 1 and. 2, the forwardflange 7 of the lens holder 6 is' diminished in width from the uppervertical median portion of the flange to the loweriverticalmedianportion thereof. In other words, the upper portion 68 of the said flange7'reaches downwardly to .a point in about the same horizontal plane asthe upper portion of the forward end of the reflector 4. I'nthehorizontal plane of the'lamp 2 and 70 extending slightly below saidplane is the 4 fully transparent portion 8 of the lens 5, the remainderof the said lens 5 being frosted or being colored and thereby renderedtransated by .9 in Fi -are 2. It

and translucent portion 9 of the lens 5 is disposed below thefullytransparent portion 8 and also atopposite sides of said portion 8, theshape of the portion '9 being preferably that of a crescent asillustrated in Figure2, and consequently the portion 9 being of acharacter to retard the passage of light rays will effectively preventglare in the line of. the vertical center of the headlight and also 8 atopposite sides of said line, and this'notwithstanding the roadway infront of the headlights will be ade uately illuminated. It will beapparent rom the foregoing that my novel headlight while practicallyadvantageous as stated, is simple and inexpensive in. construction and1n general. is

well adapted towiths'tand the usage to which headlights are ordinarilysubjected.

I have exfilicitly described the present and preferre ;embodiment of myinvention, in order to im art a full, clear and exact understanding othe said embodiment. I do not'desire, however, to be understood aslimitin myself to the structure shown ,and-descri ed, my invention beingdefined by my appended claim within the scope of which modifications maybe made without depar- Having described my invention, .what 1 5 claimand desire to secure by Letters-Patent, is:-

In a headlight and in combination, a reflector closed at its'rear endand open at itsforward end and tapered toward said rear end andgenerally inclined downwardly and forwardly, a lamp the rear end portionof the reflector, and a lens opposed to and arranged about the forwardopen end of the reflector and having an upper fully transparent verticalcentral portion, the upper part of which is in the same horizontal planearea of the fully transparent portion and the said major portion of thelens corresponding to the area of the forward end of the reflector, witha lens holder mounted on the 15 forward portion of the casing and havinga front flange, said flange tapered in width from the upper portion ofits vertical median line to the lower portion of said vertical medianline and having the lower edge 20 of its upper portion flush with theforward end of the upper portion of the reflector.

In testimony whereof I aflix my signature.

LEO KENWARD.
